Both the UHMS and DAN agree that “There can never be a flying after diving
rule that is guaranteed to prevent decompression sickness completely. Rather,
there can be a guideline that represents the best estimate for a conservative . .
. surface interval for the vast majority of divers. There will always be an occa-
sional diver whose physiological makeup or special diving circumstances will
result in the bends”.
To reduce the risk of developing decompression sickness after a single no de-
compression dive, current guidelines suggest waiting 12 hours prior to expo-
sure to atmospheric pressures equivalent to 1,000 feet (330 meters) above sea
level, or greater. When repetitive dives are conducted during the same day, or
period of days, it is suggested that the interval be increased to a minimum of
24 hours. Note that land travel to higher elevations after diving must also be
considered as an exposure to altitude.
MORE ABOUT ALTITUDE DIVING
WARNING: Diving at high altitude requires special knowledge
of the variations imposed upon divers, their activities, and
their equipment by the decrease in atmospheric pressures.
Oceanic recommends completion of a specialized Altitude
training course by a recognized training agency prior to diving
in high altitude lakes or rivers.
